If you go back to the home page you'll find the DIY section which should have all the information you need. There are often pictures to help guide you. The articles may not be for your specific model but you should be able to make the adjustments easily.

Many MB DIY'ers draw the old oil out thru the dipstick tube and since the filter is on top there's no need to jack up the car. Of course, you need a suction device for that which is mentioned in the articles.

There are also DIY sections at other MB sites such as:
www.benzworld.org

Good luck
